CHICAGO (WLS) -- Governor JB Pritzker donated $51.5 million to a campaign for a graduated tax constitutional amendment.
The money is in addition to the $5 million donation the governor made last December.
Illinois voters will decide if the graduated income tax plan becomes law on November 3.
Madison Hopkins from the Better Government Association disused Pritzker's move.
"The presidential election will be the marquee race on the ballot this November but in Illinois the most expensive and noisy campaign likely will center on the battle to overhaul the state income tax and require the rich to pay more every year," the Better Government Association recently wrote.
Hopkins said to expect political ads about the ballot measure to flood the airwaves before the November election.
